well I got the 4000 to work up to a point its complaining about memory error no matter what cpu or ram stick I put in it. (no matter what size always same error) its on the table on the side. annoyingly I will have to scrutinize the board and probably just recap the old betty to make sure I am...

Item was sold in parts, this is no longer valid. 04022024

the only "glitch" as seen on the picture is the only one seen on the monitor, that is correct.

200$ Neg. on offer, a 1987 Compaq Laptop 386/20 with the carrier "Compaq" bag! the system runs, floppy doesn't read/write, it has a type 45 Hard drive in it (untested) and comes with diskettes, a manual and a two-button MS serial mouse. There is a small "glitch on the monitor top center" I am...

check your PM

well I have quite a few drives in boxes. let me see if I have a Tandom TM-1 head for you. hit me in PM please as a reminder.

not likely no, Larry's suggestion above is very good, and if the issue continues I would look at the component on the board "the read circuit" from the schematics of the service manual of the floppy drive. maybe you have a blown part or dead cap or something. if you don't have the service...

Out of alignment is possible, but in my experience more often than not it is one of two things; The TRS-80 model 3 drives are single-sided with the read/write head on the bottom of the diskette and a felt pad on the top to counter pressure the head "holding" the media flat on the head. this felt...

If Larry Doesnt Sort you out, I have ROms for Model 3's as well
